- the forced ventilation member 131 provided with the heat exchange element 132 is closely mounted to the sidewall of the housing 110 that is in the indoor side of the building. That is, because the forced ventilation member 131 is disposed at a position spaced apart from a sidewall of the housing 110 that is disposed outdoors, outdoor cold or hot air can be prevented from being directly transferred to the heat exchange element 132 . Thus, heat exchange efficiency can be prevented from being rapidly reduced, especially considering the characteristics of the apparatus in which supply of air and exhaust of air are conducted at the same time.
- the air flow sensor 150 measures the flow and pressure of air, and the control unit 140 controls the supply fan 133 a and the exhaust fan 133 b based on the result of the measurement of the air flow sensor 150 , thus adjusting the flow rat of air.
Abstract
Description
- The present invention relates, in general, to hybrid ventilation apparatuses capable of both natural and forced ventilation and, more particularly, to a hybrid ventilation apparatus capable of both natural and forced ventilation in which, in the case of a natural ventilation mode, a worm gear is rotated in a normal direction by drive force of a drive unit under the control of a control unit such that a pressing member engages with a rotation guide protrusion and rotates a damper, thus opening a flow passage, and then the worm gear is reversely rotated by drive force of the drive unit to return the pressing member to its original position, thus allowing a user to rotate a roller upwards or downwards, thereby rotating the damper such that the degree the flow passage opening can be adjusted, whereby rapid inflow of outdoor air can be blocked, and a cold graft phenomenon, in which the temperature of indoor air rapidly drops, can be prevented.
- Generally, in structures such as buildings or apartments, windows are mainly used to ventilate contaminated indoor air. However, such a ventilation method is disadvantageous in that outdoor air is rapidly drawn indoors and air conditioned indoor air is easily exhausted through a window. This results in low thermal efficiency.
- In an effort to overcome the above-mentioned problem, a hybrid ventilation apparatus is proposed in Korean Patent Registration No. 0964979.
- In this conventional technique, a mounting plate having a through hole is installed in a housing. An on-off plate having a through hole therein is provided on the mounting plate. When the on-off plate is operated by a motor so that the through hole of the on-off plate is aligned and communicated with the through hole of the mounting plate, natural ventilation is conducted. Forced ventilation is carried out in such a way that indoor air and outdoor air are drawn by a supply fan and an exhaust fan, a heat exchanger exchanges heat between the indoor air and outdoor air, and then the heat exchanged air is discharged indoors and outdoors.
- As such, in the conventional technique, when natural ventilation is required, the motor is operated to horizontally communicate the through hole of the mounting plate with the through hole of the on-off plate. However, it is impossible for a user to adjust the degree of opening of the through holes depending on airflow conditions. Therefore, the conventional apparatus cannot cope with strong wind. In the event of rain, rainwater may enter the housing, thus causing a malfunction of the apparatus. Furthermore, because low temperature outdoor air is directly drawn indoors and the temperature of indoor air rapidly decreases, there is a problem of low thermal efficiency.
- In addition, the heat exchanger is installed on a base plate and is brought into contact with a sidewall of the housing that is disposed outdoors. Therefore, high or low temperature outdoor air is directly applied to the heat exchanger. Thereby, heat exchange efficiency of the heat exchanger is markedly reduced. Moreover, a severe dew condensation phenomenon is caused, and mildew forms, thus affecting the health of the user. Furthermore, a filter can filter out coarse dust from outdoor air but cannot remove fine dust such as yellow dust. If such fine dust enters the heat exchanger and contaminates it, the lifetime thereof is reduced. Furthermore, because the total heat exchanger contracts and expands depending on the variation in temperature of outdoor air, the airtightness cannot be ensured. As a result, the product reliability is markedly reduced, considering characteristics of the apparatus in which supply of air and exhaust of air are conducted at the same time.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a hybrid ventilation apparatus capable of both natural and forced ventilation in which, in the case of a natural ventilation mode, a worm gear is rotated in a normal direction by drive force of a drive unit under control of a control unit so that a pressing member which protrudes from the worm gear engages with a rotation guide protrusion and rotates a damper, thus opening a flow passage, and then the worm gear is reversely rotated by drive force of the drive unit to return the pressing member to its original position, thus allowing a user to rotate a roller upwards and downwards and rotate the damper so that the degree of opening of the flow passage can be adjusted, whereby rapid inflow of outdoor air can be blocked, and a cold graft phenomenon in which the temperature of indoor air rapidly drops can be prevented.
- Another object of the present invention is to provide a hybrid ventilation apparatus capable of both natural and forced ventilation in which a forced ventilation member provided with a heat exchange element is brought into contact with a sidewall of a housing that is disposed in the indoor side of the building so that the heat exchange element can be prevented from being deformed by variation in temperature of outdoor air.
- In order to accomplish the above objects, the present invention provides a hybrid ventilation apparatus for naturally and forcedly ventilate indoor air of a building, including: a housing having a base plate on which a natural ventilation unit for naturally ventilating indoor air of the building and a forced ventilation unit for forcedly ventilating the indoor air are installed, and a cover mounted to the base plate, the cover receiving and protecting the natural ventilation unit and the forced ventilation unit therein, with an inlet port provided on the cover, the inlet port being open downwards; a natural ventilation unit installed in the housing, the a natural ventilation unit having therein flow passage communicating with the inlet port, wherein a worm gear is rotated in a normal direction by drive force of a drive unit under control of the control unit and, simultaneously, pressing members that protrude from the worm gear engage with rotation guide protrusions and rotates dampers and open the flow passage, and after the flow passage has been opened, the worm gear is reversely rotated by drive force of the drive unit to return the pressing members to original positions thereof, and rollers and are rotated upwards or downwards by a user so that the dampers and are rotated, whereby a degree of opening of the flow passage is adjusted such that the indoor air is naturally ventilated through the flow passage; and a forced ventilation unit comprising a forced ventilation member provided above the natural ventilation unit and closely mounted to a sidewall of the housing that is in an indoor side of the building, the forced ventilation unit having a heat exchange element therein, the forced ventilation unit comprising a supply fan and an exhaust fan rotating to forcedly ventilate the indoor air under control of the control unit.
- According to the present invention, in the case of a natural ventilation mode, a worm gear is rotated in a normal direction by drive force of a drive unit under control of a control unit so that a pressing member engages with a rotation guide protrusion and rotates a damper, thus opening a flow passage. Thereafter, the worm gear is reversely rotated by drive force of the drive unit to return the pressing member to its original position, thus allowing a user to rotate a roller upwards and downwards and rotate the damper so that the degree of opening of the flow passage can be adjusted. Thereby, rapid inflow of outdoor air can be blocked, and a cold graft phenomenon in which the temperature of indoor air rapidly drops can be prevented.
- Furthermore, a forced ventilation member, in which a heat exchange element is installed, is brought into contact with a sidewall of a housing that is disposed in the indoor side of the building. Thus, the heat exchange element can be prevented from being deformed by variation in temperature of outdoor air, whereby the airtightness of the apparatus can be ensured. In addition, the apparatus according to the present invention includes a filter which has a double filtering structure in which a high efficiency filter is covered with a prefilter. The filter can filter out not only coarse dust but also fine dust such as yellow dust from outdoor air, thus preventing the heat exchange element from being contaminated, and thereby preventing the lifetime of the heat exchange element from being shortened. Therefore, product reliability can be enhanced. Furthermore, in the present invention, an inlet port of the housing is open downwards. Hence, even in the case of rain, which can cause malfunction, rainwater can be prevented from entering housing.

ventilation apparatus 100 further includes anair flow sensor 150 which is installed in an end of theflow passage 121 a′ and measures the flow and pressure of air. - The
ventilation apparatus 100 further includes acarbon dioxide sensor 160 which is provided at a predetermined position in thehousing 110. Thecarbon dioxide sensor 160 measures the degree of pollution of indoor air to determine whether operating the forcedventilation unit 130 under the control of thecontrol unit 140. - The operation of the apparatus according to the present invention having the above-mentioned construction will be explained.
- When natural ventilation is required depending on the degree of pollution of indoor air that is measured by the
carbon dioxide sensor 160, as shown inFIGS. 8 through 12 , thenatural ventilation unit 120 is operated under the control of thecontrol unit 140 in response to the result of measurement using thecarbon dioxide sensor 160 and a temperature sensor (not shown). Thenatural ventilation unit 120 operates themotor 123 a of thedrive unit 123 in the normal direction under the control of thecontrol unit 140. - Then, the
pressing members 123 c, which are connected to theworm gear 123 b and extend in a direction crossing the output shaft of themotor 123 a, rotate in the normal direction and press correspondingfirst surfaces 122 c′ of the rotation guideprotrusions 122 c of thedampers rotation guide shafts 122 b provided with the rotation guideprotrusions 122 c rotates in the corresponding rotation guide holes 121 c. The on-offplates 122 a which are integrally provided with the respectiverotation guide shafts 122 b rotate in the normal direction, so that edges of the on-offplates 122 a move away from the flowpassage closing protrusions 121 b. As a result, theflow passage 121 a′ of thenatural ventilation members motor 123 a of thedrive unit 123 is rotated in the normal direction to 90° from the set state such that the on-offplates 122 a of thedampers ventilation bodies 121 a. - After the
flow passage 121 a′ of thenatural ventilation members dampers motor 123 a of thedrive unit 123 is reversely operated under the control of thecontrol unit 140, theworm gear 123 b coupled to the output shaft of themotor 123 a is also reversely rotated. Thepressing members 123 c connected to theworm gear 123 b is reversely rotated by the reverse rotation of theworm gear 123 b and is brought into contact withsecond surfaces 122 c″ of the rotation guideprotrusions 122 c. - Through the
inlet port 112′ which is formed in thecover 112 of thehousing 110 and is open downwards, outdoor air is drawn into theflow passage 121 a′ that has been opened through the above-mentioned process. The outdoor air is supplied into the interior of the building via the airflow sensing sensor 150 provided on the end of theflow passage 121 a′ after passing through the prefilter F. - When outdoor air is drawn into the
flow passage 121 a′, the user can adjust the degree of opening of theflow passage 121 a′. For this, as shown inFIGS. 13 through 15 , the user rotates theroller 124 b of the tworollers manual adjustment unit 124 that protrudes outwards through thehousing 110. - When the
roller 124 b is rotated, the rotating force of theroller 124 b rotates both theroller 124 b connected to theroller 124 b by theconnection shaft 124 c, and thetiming belts 124 a wrapped around therespective rollers rotation guide shafts 122 b of thedampers timing belt 124 a are rotated, whereby the on-offplates 122 a are rotated. As a result, the degree of opening of theflow passage 121 a′ can be adjusted. - Here, when the
dampers protrusions 122 c which protrude from the ends of therotation guide shafts 122 b move away from the corresponding pressingmembers 123 c by an angle at which thedampers - In the
manual adjustment unit 124, thedampers rollers pressing members 123 c of thedrive unit 123 and the rotation guideprotrusions 122 c of thedampers dampers protrusions 122 c come into contact with the corresponding pressingmembers 123 c. As such, because the degree of opening of theflow passage 121 a′ can be adjusted by rotating thedampers rollers flow passage 121 a′ through theinlet port 112′, thus preventing rapid variation in temperature of indoor air. - Furthermore, the angle to which the
dampers motor 123 a under the control of thecontrol unit 140 in response to thecarbon dioxide sensor 160, the temperature sensor (not shown) and theair flow sensor 150. - As shown in
FIG. 16 , while the natural ventilation operation is carried out, if the degree of pollution of indoor air that is measured by thecarbon dioxide sensor 160 is not improved, or if a forced ventilation operation is required by the user, as shown inFIG. 17 , the forcedventilation unit 130 is operated under the control of thecontrol unit 140. First, themotor 123 a of thedrive unit 123 is reversely operated by thecontrol unit 140. Then, theworm gear 123 b coupled to the output shaft of themotor 123 a is also reversely rotated. - Then, the
pressing members 123 c which are connected to theworm gear 123 b in the direction crossing the output shaft of themotor 123 a are also reversely rotated. At this time, if thedampers pressing members 123 c directly press thesecond surfaces 122 c″ of the rotation guideprotrusions 122 c of thedampers - If the
dampers manual adjustment unit 124, thepressing members 123 c are rotated to a predetermined angle before pressing thesecond surfaces 122 c″ of the rotation guideprotrusions 122 c of thedampers - When the
pressing members 123 c press thesecond surfaces 122 c″ of the rotation guideprotrusions 122 c of thedampers rotation guide shafts 122 b provided with the rotation guideprotrusions 122 c are rotated in the corresponding rotation guide holes 121 c. Then, the on-offplates 122 a which are integrally provided on therotation guide shafts 122 b are reversely rotated, and the edges of the of-offplates 122 a are brought into close contact with the flowpassage closing protrusions 121 b, thus closing theflow passage 121 a′ of thenatural ventilation members motor 123 a of thedrive unit 123 is reversely rotated to 90° from the set state such that the on-offplates 122 a of thedampers ventilation body 121 a. - After the
flow passage 121 a′ is closed by the rotation of thedampers motor 123 a of thedrive unit 123 is rotated in the normal direction under the control of thecontrol unit 140, theworm gear 123 b coupled to the output shaft of themotor 123 a is rotated in the normal direction. Then, thepressing members 123 c connected to theworm gear 123 b are rotated in the normal direction by the normal-directional rotation of theworm gear 123 b and are thus brought into contact with thefirst surfaces 122 c′ of therotation guide protrusion 122 c. - After the
flow passage 121′a has been closed by the rotation of thedampers supply fan 133 a and theexhaust fan 133 b of the forcedventilation unit 130 are operated under the control of thecontrol unit 140. When outdoor air is drawn into theinlet port 112′ of thehousing 110 by the rotation of thesupply fan 133 a, thefilter 134 provided on the front end of theinlet passage 131 a filters out impurities from the air. - The
filter 134 has a double filtering structure in which thehigh efficiency filter 134 a is covered with theprefilter 134 b. Thefilter 134 functions to filter out yellow dust or fine dust and sterilize air. Outdoor air that has passed through thefilter 134 is moved to theheat exchange element 132 which is installed at the junction between theinlet passage 131 a and theexhaust passage 131 b of the forcedventilation member 131 - Furthermore, indoor air is drawn into the front end of the
exhaust passage 131 b through a grille (not shown) by rotation of theexhaust fan 133 b and then is moved to theheat exchange element 132. In theheat exchange element 132, heat exchange between high temperature indoor air moved to theexhaust passage 131 b and low temperature outdoor air drawn into theinlet passage 131 a is performed. That is, low temperature outdoor air receives heat from high temperature indoor air. Thus, the outdoor air that has been increased in temperature and the indoor air that has been reduced in temperature respectively move to the rear ends of theinlet passage 131 a and theexhaust passage 131 b. - The case where the temperature of outdoor air is lower than that of indoor air refers to winter. In the case of summer, the temperature of outdoor air should be explained as being higher than that of indoor air.
- The
heat exchange element 132 is disposed at the junction between theinlet passage 131 a and theexhaust passage 131 b of the forcedventilation member 131. The forcedventilation member 131 provided with theheat exchange element 132 is closely mounted to the sidewall of thehousing 110 that is in the indoor side of the building. That is, because the forcedventilation member 131 is disposed at a position spaced apart from a sidewall of thehousing 110 that is disposed outdoors, outdoor cold or hot air can be prevented from being directly transferred to theheat exchange element 132. Thus, heat exchange efficiency can be prevented from being rapidly reduced, especially considering the characteristics of the apparatus in which supply of air and exhaust of air are conducted at the same time. - Outdoor air which moves to the rear end of the
inlet passage 131 a through theheat exchange element 132 is drawn into the interior of the building via theair flow sensor 150 provided in theflow passage 121 a′ of thenatural ventilation member 121′. Simultaneously, indoor air which moves to the rear end of theexhaust passage 131 b through theheat exchange element 132 is moved to theflow passage 121 a′ of thenatural ventilation member 121′. Here, because theflow passage 121 a′ is closed by thedamper 122, indoor air is exhausted to the outside only through theinlet port 112′. - The
air flow sensor 150 measures the flow and pressure of air, and thecontrol unit 140 controls thesupply fan 133 a and theexhaust fan 133 b based on the result of the measurement of theair flow sensor 150, thus adjusting the flow rat of air. - Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
